' Applcatieny filed November 13, 192.22-, `Serial No., 6015,566. i

To all whom t ma?) @fof/Learn.'

Be it known that I, FRANK A. RYDER, a. citizen of the United States, anda resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful' Improvements inEnvelopes, of which the following is a specification.

My invention relates yto envelopes, and more 4particularly to the typelof envelope with an openable portion or flap for inspection of thecontents by the postal authorities.

A primary yobject of my invention is t provide an envelope of the type',referred. to having means for securely interlocking and retaii'iing theinspection yflap in position on the envelope, to prevent accidental ofthe contents, during filling and tr .A

Other objects will appearv hereinafter.

The invention consists inthe combinations and arrangements of partsherein-after described and claimed. n

rlhe invention will` be best4 understood by reference to theaccompanying drawings forming a part ofthisspecilication, and in which,

Fig. 1, is a view of theblanlr which one form of envelopeembodying'my'invem tion may be constructed; 'f

Fig. 2, is a view showing the envelope completed, with the sealing flapopen;

Fig. 8, is a view showing the sealing flap in closed position, but. theremovable end or inspection flap withdrawn;

Fig. 4, is an enlarged vertical sectional view taken on line 4 4- ofFig. 2;

Fig. 5, shows. a modified form of blank from which the envelope may beconstructed;

Fig. 6, is a view showing the modified form of envelope completed, withthe sealing flap open;

Fig. 7 is a view showing the sealing flap in closed position but theopenable portion or inspection flap withdrawn, and

Fig. 8, is an enlarged vertical sectionalk view taken on line 8 8 ofFig. 6.

The form of my invention illustrated in Figs. 1 to l comprises a facemember or front portion 6 and a back portion or flap 7 folded up fromthe lower edge of said front portion, an end portion or flap 8 beingfolded between portions 6 and 7 and fastened in position by adhesivemeans 9 provided on the back portion, or with any suitable fasteningmeans. A second end portion or inspection flap 10 is folded between theportions 6 andg7 and is provided with a lip 1.1 at' its upper endwhichA` is folded over the back portion 7 and has means 12, suchas a fewdrops of adhesive material, or any other snitable means, which fas'tensthe lip 11 down on said end portion 10, saic'lfastening means engagingin a notch or flaring slot 13 provided in the -npper edge of said backportion and bearing behind a tongue 121' on said back portion to retainthe Aend portion securely in position, during filling ofthe envelope,and releasably for inspection.' A sealing Hap 15 with adhesive'means 16isv provided to close the envelope.

The modified form of envelope shown' in Figs. 5 to 8 is similar to thepreceding forni,y and comprises the front and back portions 6 and 7 anend portion 8 fastened to the back portionV by adhesive means 9! also,the openab-le end portion or inspection flap 10 provided with lip 11folded over the back portion and fastened thereover with fastening means12, which fixes the folded lip 11 down onto the end portion, said means11 and 1,2* engaging in notch or flaring slot 18 back of the tongue1li'.r In this form the openable end portion or' inspect-ion flap er:-`tends to the middle of the envelope, and the cooperating lip, thefastening means, and the notch and tongue are therefore positioned nearthe upper middle portion of this envelope instead of being locatedadjacent the upper end near the openable end portion, as in thepreceding form.

The envelope is put on the market with the openable end portion 10placed in position between the front and back portions and the lipvllfastened down over the back por.' a;

tion, with the fastening means 12 engaging behind the tongue 14; andwhen the user' of the envelope fills the same it is found that theinterlocking means 11, 12, 13, and 14C, provides a very secure means forfirmly retaining the 'end flap 10 in closed position during filling andduring subsequent tra-nsmission, thereby preventing the unpleasantaccidental discharge often occurring with the usual inspection envelope,both during filling and during transit. .When it is desired to withdraw*the enclosed matter it is merely necessary to place the fingers inbetween the inspection flap l0 and the back portion 7 thereby movingdown the unsealed upper corner of the back portion 7 with its tongue 14which is thereby disengaged from PATE-Nr cir-Fica.;

Y the fastening means 12, thus permitting they withdrawing of theinspection iap lO and the removal of the enclosed matter.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without.

departing from the spirit of the invention. I, therefore, do not wish tobe limited to the precise details of construction set forth, but desireto avail myself of such variations and modifications as come within thescope of the appended claims.

Having described my invention, what I claim as new and desire to secureby Letters Patent is: A

l. An envelope provided with a front and having a back portion and anend portion extending from said front, a notch cut in the edge of one ofsaid portions to provide a holding tongue, and a lip on the other ofsaid portions overlapping said tongue and having means for fastening itdown and for engaging in said notch behind said tongue to hold said endin position during filling but to permit ready withdrawal of said endfor inspection.

2. An envelope having front and back portions, a notch cut in said backportion forming a tongue, and an end portion folded between said frontand back portions and having an extension overlapping said back portion,said extension and end portion being provided with means engaging insaid notch against said tongue for releasably retaining said end portionin position.

3. An envelope having front and back said back portion, an end portionat said end provided with a folded extension held down by interlockingmeans, and tongue means at the upper edge of said back` portio-n forengaging behind said interlocking means to hold said end portion duringfilling and being releasable therefrom by an outward movement of saidback portion to permit withdrawing said end portion.

4. An envelope having front and back portions and end portionsfoldedtherebetween, means for fixing one end portion to the backportion, a sealing flap for fastening over said back portion, a lip onthe other end portion foldab-le over said back portion, a slot andtongue on the upper edge of said back portion, and adhesive means forfastening the folded lip on said end portion, said adhesive. means beingpositioned within said slot and with the surrounding part of said lipengaging behind said tongue for sccurely holding said end portion inposition during filling and permitting convenient release thereof forinspection.

In testimony whereof I have signed my name to. this specification in thepresence of two subscribing witnesses.
